Abstract
싸이오닐 클로라이드와 무수에탄올 존재 하에서 사이클로펜탄온 또는 아세톤을 호모커플링 반응을 진행시키어 화합물 2-(1-사이클로헥센일)-사이클로헥산온(1), 바이사이클로펜틸이딘-2-온(2) 그리고 4-메틸-3-펜텐-2-온(3)을 효율적으로 제조하였다.

A simple and efficient method for homocoupling of cycloketones and acetone is described. 2-(1-Cyclohexenyl)-cyclohexanone (1), bicyclopentyliden-2-one (2) and 4-methyl-3-penten-2-one (3) were synthesized from cyclohexanone, cyclopentanone and acetone respectively, in the presence of thionyl chloride in anhydrous ethanol.
